Abstract

PURPOSE:To obtain a sun screening cosmetic having excellent utility, stability, safety and ultraviolet light preventing effects, by blending a cosmetic with specific mica powder. CONSTITUTION:A cosmetic is blended with one or more selected from the group consisting of natural phlogopite powder, biotite powder and synthetic mica powder containing one or more metallic elements selected from iron, zinc, titanium, manganese, chromium, cobalt, nickel, selenium and silver. The amount of the mica powder blended in the cosmetic is 1-100wt.%. The blend is mixed with other cosmetic components (e.g. talc, iron oxide or liquid paraffin) for ordinary use to give aimed substance. The aimed substance can be prepared into a state such as powder, lump, cake, pencil, stick, ointment, solution, milky lotion or cream. Cosmetic blended with specific mica powder have excellent slipperiness, spreadability on the skin and transparent feeling free from uneven application, whitening and deterioration by heat and light.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides natural phlogopite powder, biotite powder, and one kind of metal elements such as iron, zinc, titanium, manganese, chromium, cobalt, nickel, selenium, and silver. Or a sunscreen with good usability, finish, stability, safety, and UV protection effect, which is made by blending one or more types selected from the group consisting of synthetic mica powder containing two or more types in the crystal lattice. Regarding cosmetics.

[Prior Art] In conventional sunscreen cosmetics, in order to enhance the sunscreen effect, ultraviolet absorbers such as paradimethylbenzoic acid ethylhexyl ester and oxybenzone are blended, and powders such as finely divided titanium dioxide and zinc oxide are blended. It's been coming.

[Problems to be Solved by the Invention] However, when an ultraviolet absorber is blended, there are problems with coloring due to light or thermal deterioration or with safety.

Further, when fine particles of titanium dioxide or zinc oxide are used, there are disadvantages in that the skin looks whitish, the skin is not slippery, the spreadability is poor, and the reading becomes uneven.

[Means for solving the problem] In view of the above circumstances, the present inventors have conducted intensive research and have found that
Cosmetics containing a specific mica powder have good slippage, so they have good spreadability when read, are smooth, transparent, do not look whitish, do not deteriorate due to heat or light, and have good sunscreen effects. We have discovered that this is a sunscreen cosmetic with excellent properties, and based on this knowledge, we have completed the present invention.

That is, the present invention provides natural phlogopite powder, biotite powder, and synthetic mica containing one or more of the following metal elements in the crystal lattice: iron, zinc, titanium, manganese, chromium, cobalt, nickel, selenium, and silver. This sunscreen cosmetic is characterized by containing one or more types selected from the group consisting of powders.

Hereinafter, the configuration of the present invention will be explained in detail.

The basic structural formula of natural phlogopite and biotite used in the present invention is expressed as KMg3(AQ, 5i30+o) (OH)2. I'm taking it. Phlogopite has a Fe mole/A1 mole value of up to about 0.3, and biotite has a roughly larger value. The higher the Fe content, the higher the sunscreen effect.

Natural phlogopite comes from Canada, Finland, Sri Lanka, India, Madagascar, Iran, China, North Korea, etc. Natural biotite comes from India, Japan, etc. These crystals may be pulverized by either dry pulverization or wet pulverization.

The synthetic mica powder used in the present invention contains one or more metal elements of iron, zinc, titanium, manganese, chromium, cobalt, nickel, selenium, and silver in its crystal lattice.
The base material is synthetic mica such as fluorine phlogopite, potassium tetrasilicon mica, Ha tetrasilismic mica, Ha or Li taeniolite, and Ha or Li hectorite. The manufacturing method uses synthetic mica raw materials such as silica, alumina, magnesia, potassium silicofluoride, and potassium carbonate, as well as zinc oxide,
Oxides, nitrates, chlorides, sulfates, and carbonates of the above metal elements such as nickel carbonate, iron oxide, manganese oxide, and cobalt oxide are mixed and the ore mass obtained by melt synthesis is subjected to dry or wet pulverization. The synthetic mica powder of the present invention can be obtained by micronization. Specifically, to take fluorine phlogopite as an example, potassium silicofluoride 3.4
Weight%, iron oxide 16.1% by weight, magnesia 18.6% by weight, silica 46.2% by weight, alumina 15.7% by weight
Fe 5.3
% of fluorine phlogopite is obtained.

The content of iron, zinc, titanium, manganese, chromium, cobalt, nickel, selenium, and silver in the synthetic mica used in the present invention is preferably 2 to 14% by weight.

If it is less than 2% by weight, the UV protection effect will not be sufficient, and a structure with 14 overlapping parts will not be possible due to the structure of synthetic mica.

The particle size of the natural phlogopite, biotite, and synthetic mica used in the present invention is suitably 1 to 10 μm in terms of average particle size in terms of spherical shape. 1
If it is less than 10 μm, the transparency will decrease, which is not preferable, and if it exceeds 10 μm, it will feel rough, which is not preferable. The shape depends on the application, but the thickness is 0.05 to 2μ in the thickness direction and 2 to 60μ in the surface direction.
A plate-like one is preferable because it has a transparent appearance.

The amount of the above-mentioned natural phlogopite, reference mica, and synthetic mica in cosmetics is 1 to 100% by weight in the cosmetics.

The sunscreen cosmetics of the present invention include a wide range of sunscreen cosmetics such as body, facial, makeup, hair, etc., such as foundation, whitening powder,
Suitable for eye shadow, blusher, makeup base, nail enamel, eyeliner, lipstick, sun oil, emulsion, cream, lotion, etc.

When incorporated into cosmetics, the mica powder of the present invention may be subjected to silicone treatment, metal soap treatment, fatty acid treatment, surfactant treatment, or treatment with acids, alkalis, or inorganic salts, or combinations thereof. It may be blended after the treatment.

The sunscreen cosmetic of the present invention may contain any conventionally known components in addition to the above-mentioned essential components.
